Empirical studies of the relationship between aspects of the landscape and human emotions have been fruitful over the last few decades. In fact, we are awash in data that describes a correlation between natural landscapes and positive human feelings. While this plethora of data has been useful to various disciplines, it has not lead to an explanatory theory as to why and how the landscape should have this affect. This paper proposes that the discipline of evolutionary psychology provides an explanatory theory.

Cycads are the most endangered of plant groups based on IUCN Red List assessments; all are in Appendix I or II of CITES, about 40% are within biodiversity ‘hotspots,’ and the call for action to improve their protection is longstanding. We contend that progress in this direction will not be made until there is better understanding of cycad pollen, seed and tissue biology, which at the moment is limited to relatively few (<10%) species.
Increasingly, humans are an urban species prone to ‘plant blindness’. This demographic shift and situation has implications for both individual and collective perceptions of nature, as well as for addressing ‘ecophobia’ and encouraging ‘biophilia’ through education. Contemporary humanity occupies a world in which extensive physical change, both in the landscape and its related organisms, is occurring . Education-related debates on these issues links to the noted phenomenon of a ‘bubble wrap generation’ growing up within ‘nature-deficit’ childhoods in ‘megalopolitan cities’.
Botanical gardens devote their resources to the study and conservation of plants, as well as making the world's plant species diversity known to the public. These gardens also play a central role in meeting human needs and providing well-being. In this minireview, a framework for the integrated missions of botanical gardens, including scientific research, in/ex situ conservation, plant resource utilization, and citizen science are cataloged.
Early botanic gardens served medicine, and then they became important for
biological research as well as for the transfer of crop species around the globe.
Today, they are important sites for outreach and education, but globally their most
crucial role may be in conservation. Will they be able to save every plant known to
Taxonomy is a scientific discipline that has provided the universal naming and classification system of biodiversity for centuries and continues effectively to accommodate new knowledge. A recent publication by Garnett and Christidis expressed concerns regarding the difficulty that taxonomic changes represent for conservation efforts and proposed the establishment of a system to govern taxonomic changes.
Recent studies have shown that the use of native plants by landscape architects and contractors in the southeastern United States has increased as has the clientele interest level in native plants. Recommendations to increase the use of native species by the landscape industry in this region include increasing the number of nurseries carrying native plants and the quantities and species currently available.
Integrating invasive species policies across ornamental horticulture supply chains to prevent plant invasions
Ornamental horticulture is the primary pathway for invasive alien plant introductions. This paper critically appraises published evidence on the effectiveness of four policy instruments that tackle invasions along the horticulture supply chain: pre- border import restrictions, post- border bans, industry codes of conduct and consumer education.
The Value of Pollinators and Pollinator Habitat to Rangelands: Connections Among Pollinators, Insects, Plant Communities, Fish, and Wildlife
Native pollinating bees are a vital component of the biologically diverse plant and animal community which is critical to healthy, ecologically functional range landscapes. There are more than 20,000 species of bees world-wide. They exist on every continent except Antarctica. Over 4,000 species are known in the United States, most of which are solitary ground-nesting bees.
